An experimental particle physicist answers speculations about creation and fine-tuning

6 Comments

I was corresponding with Dr. Michael G. Strauss recently regarding some comments that my previous articles on the kalam, fine-tuning and habitability arguments had drawn. Dr. Strauss is a tenured professor but he also does research on particle physics.

I wanted to draw your attention to a lecture given by Dr. Strauss to the students at Stanford University. In the lecture, he gives 3 arguments from the progress of science that support the conclusion that the universe was created and designed by an intelligent agent of immense power.

I highly recommend this lecture, entitled “Scientific Evidence for the Existence of God”.

Dr. Strauss is not a Christian philosopher or debater – he is a practicing physicist with a stack of publications, who is excited by scientific discoveries that confirm the existence of God.

Here is an outline of the lecture:

What does science tell us about God?
– the discoveries of Copernicus made humans less significant in the universe
– the discoveries of Darwin should that humans are an accident
– but this all pre-modern science
– what do the latest findings of science say about God?

Evidence #1: the origin of the universe
– the steady state model supports atheism, but was disproved by the latest discoveries
– the oscillating model supports atheism, but was disproved by the latest discoveries
– the big bang model supports theism, and it is supported by multiple recent discoveries
– the quantum gravity model supports atheism, but it pure theory and has never been tested or confirmed by experiment and observation

Evidence #2: the fine-tuning of physical constants for life
– there are over 100 examples of constants that must be selected within a narrow range in order for the universe to support the minimal requirements for life
– example: mass density
– example: strong nuclear force (what he studies)
– example: carbon formation

Evidence #3: the fine-tuning of our planet for habitability
– the type of galaxy and our location in it
– our solar system and our star
– our planet
– our moon

What Dr. Strauss thinks about science

As you listen to the lecture, pay close attention to the fact that it is the progress of science that has disproved atheism and given support to theism. Atheism is based on old science. And people who continue to cling to atheism against the new evidence must resort to speculations that are either not testable at all, or not confirmed by experimental testing.

Let’s take a look at two of the speculations that sound scientific, but aren’t confirmed by any research. The first is quantum mechanics (i.e. – vacuum fluctuation model). It argues that the universe is an event without a cause, because there is an unobservable hyper-universe that spawned our universe. The second is a response to the fine-tuning. It argues that there are an infinite number of unobservable universes that are not fine-tuned, and we just happen to be in the fine-tuned one.

Notice that both responses are theoretical speculations that take refuge in unobservable entities in order to escape the good experimental science that proves that there is a Creator and Designer. It’s atheism-of-the-gaps!

Vacuum fluctuation:
– offered as a response to the big bang
– what can QM do: explain how particles appear in a vacuum when the vacuum is sparked
– speculation is that this same process may explain the origin of the universe
– in order to test it, our universe would have to be contained within a larger universe, with similar laws of physics
– but there is no evidence that this unobservable hyper-universe exists

Chaotic inflationary model:
– offered as a response to the fine-tuning
– speculates that inflation may cause other universes to come into being, with different constants
– no experimental verification has been offered
– no evidence of any of these other universes

So, what we have here is a clear cut case of logical arguments and evidence for theism, vs atheist faith and wish-fulfillment. All the data we have today is for theism, but all the untestable speculating is on the part of the atheists, who have faith and hope that the progress of science will overturn what we know and replace it with the what atheists hope for. (And I haven’t even talked about the origin of life and molecular machines, etc.!)

In fact I e-mailed Dr. Strauss about these two speculations, and this was his response:

Wintery Knight,

Quantum mechanics works within the laws of physics. So if you postulate that this universe was created from QM then you must also postulate that a previous universe with similar laws existed previously.

There are a number of theories that would allow multiple universes, though none have any experimental verification. Have you read Jeff’s “Who’s Afraid of a Multiverse?” It is very good.

-Mike

I think that we need to be careful when we explore these issues of faith and science. This is not a game. We need make decisions about what is true today, not hold out hope that some discovery will be made later that validates what we want to believe.

Further study

Dr. Strauss gave a similar lecture more recently at the University of California (Santa Cruz) and in the Q&A, he actually faced questions regarding quantum mechanics and the chaotic inflationary model. You can hear him express his mistrust of theories that haven’t been proven as he urges the audience to go with the evidence, not with the self-serving speculations. Dr. Strauss takes part in a panel discussion on science and religion here.

Also on this topic is the debate between William Lane Craig and atheist physicist Victor Stenger, (audio here). Also, a lecture titled “Beyond the Big Bang”, was delivered at the University of Colorado at Boulder, in front of Victor Stenger and other physicists (audio here). There is a period of Q&A in which Bill must face challengers. These are both available on DVD. More Bill Craig debates are here.

In this published research paper from the journal Astrophysics and Space Science, William Lane Craig responds to the several naturalistic attempts to evade the implications of the kalam argument. Vacuum fluctuation, chatoric inflationary, steady state and quantum gravity models are all addressed.

Obama aims to destroy math, physics and computer science

1 Comment

Story by Christina Hoff Sommers in the Washington Post, or here on AEI. (H/T The American Enterprise Institute)

I bet you thought that Obama was pro-science, didn’t you? Nope. Not only is he directing funds towards unproven ESCR and away from useful ASCR, but he also means to destroy university education in the fields of math and science. Leftist politics is more important than science for Obama.

Here’s what he plans to do:

In an October letter to women’s advocacy groups, he declared that Title IX, the law that requires universities to give equal funding to men’s and women’s athletics, had made “an enormous impact on women’s opportunities and participation in sports.” If pursued with “necessary attention and enforcement,” the same law could make “similar, striking advances” for women in science and engineering.

That campaign pledge is hardening into policy, which ought to give people pause. In February, the Congressional Diversity and Innovation Caucus met with academic deans and women’s groups to plan for the new Title IX deployment. Nearly everyone present agreed that closing the gender gap in the laboratory is an urgent “national imperative.” What they failed to consider, however, is how enforced parity might affect American science.

To start with, consider the effects of Title IX:

Consider the situation at Washington’s Howard University. In 2007, the Women’s Sports Foundation, a powerful Title IX advocacy group, gave Howard an “F” grade because of its 24-percentage-point “proportionality gap”: Howard’s student body was 67 percent female, but women constituted only 43 percent of its athletic program. In 2002, Howard cut men’s wrestling and baseball and added women’s bowling, but that did little to narrow the gap. Unless it sends almost half of its remaining male athletes to the locker room, Howard will remain blacklisted and legally vulnerable. Former Howard wrestling coach Wade Hughes sums up the problem this way: “The impact of Title IX’s proportionality standard has been disastrous because . . . far more males than females are seeking to take part in athletics.”

Allison Kasic over at the Independent Women’s Forum writes about recent cuts at Kutztown University.

She writes:

The latest victims of gender equity appear to be men’s soccer and swimming at Kutztown University in Pennsylvania.  The school announced at the end of March that it would be cutting both sports effective at the end of this season.

…The “gender equity” law guides school’s program decisions through its rigid proportionality requirements (aka gender quotas).  For background on Title IX’s demands, read this as a starting point.  And, lo and behold, after students, parents, and coaches started asking questions about Title IX, the school admitted that many factors, including Title IX were taken into consideration.

IWF writes about Title IX quite a bit, and they have some of their pieces linked here.

UPDATE: Alison K. at the IWF sent me a couple of links on Title IX.

  • A thorough overview of Title IX’s impact on athletics is available here.
  • If you are looking for something shorter, this is basically the Cliff Notes version.

How to defend the fine-tuning argument just like William Lane Craig

32 Comments

UPDATE: Welcome visitors from Colliding Universes! Thanks for the link Denyse!

This post is the second in a two part series. In case you missed it, here is Craig’s first argument on the kalam argument.

First of all, if you’re not clear on the fine-tuning argument, click here and read Walter Bradley’s exposition of it. Dr. Walter L. Bradley (C.V. here) is the Distinguished Professor of Engineering at Baylor University. He was also a professor and department head at Texas A&M before going to Baylor. He had his Ph.D at age 24 from the University of Texas and was a tenured professor at 27.

The first argument presented by Bradley in that post is the same argument that Craig used against Hitchens in their debate. (It’s Craig’s second argument in the set of five). Bradley’s version of the argument has been presented live, in-person by Bradley at dozens of universities here and abroad, in front of students and faculty. The lecture I linked to in that post is an MP3.

The fine-tuning argument

The argument goes like this:

  1. The fine-tuning of the universe to support life is either due to law, chance or design
  2. It is not due to law or chance
  3. Therefore, the fine-tuning is due to design

What does it meaning to be fine-tuned for life?

Here are the facts on the fine-tuning:

  • Life has certain minimal requirements; long-term stable source of energy, a large number of different chemical elements, an element that can serve as a hub for joining together other elements into compounds, etc.
  • In order to meet these minimal requirements, the physical constants, (such as the gravitational constant), and the ratios between physical constants, need to be withing a narrow range of values in order to support the minimal requirements for life of any kind.
  • Slight changes to any of the physical constants, or to the rations between the constants, will result in a universe inhospitable to life.
  • The range of possible ranges over 70 orders of magnitude.
  • The constants are selected by whoever creates the universe. They are not determined by physical laws. And the extreme probabilities involved required put the fine-tuning beyond the reach of chance.
  • Although each individual selection of constants and ratios is as unlikely as any other selection, the vast majority of these possibilities do not support the minimal requirements of life of any kind. (In the same way as any hand of 5 cards that is dealt is as likely as any other, but you are overwhelmingly likely NOT to get a royal flush. In our case, a royal flush is a life-permitting universe).

Examples of finely-tuned constants

Here are a couple of examples of the fine-tuning. Craig only gave one example in the debate and didn’t explain how changes to the constant would affect the minimal requirements for life. But Bradley does explain it, and he is a professional research scientist, so he is speaking about things he worked in his polymer research lab. (He was the director)

a) The strong force: (the force that binds nucleons (= protons and neutrons) together in nucleus, by means of meson exchange)

  • if the strong force constant were 2% stronger, there would be no stable hydrogen, no long-lived stars, no hydrogen containing compounds. This is because the single proton in hydrogen would want to stick to something else so badly that there would be no hydrogen left!
  • if the strong force constant were 5% weaker, there would be no stable stars, few (if any) elements besides hydrogen. This is because you would be able to build up the nuclei of the heavier elements, which contain more than 1 proton.
  • So, whether you adjust the strong force up or down, you lose stars than can serve as long-term sources of stable energy, or you lose chemical diversity, which is necessary to make beings that can perform the minimal requirements of living beings. (see below)

b) The conversion of beryllium to carbon, and carbon to oxygen

  • Life requires carbon in order to serve as the hub for complex molecules, but it also requires oxygen in order to create water.
  • Carbon is like the hub wheel in a tinker toy set: you can bind other elements together to more complicated molecules (e.g. – “carbon-based life), but the bonds are not so tight that they can’t be broken down again later to make something else.
  • The carbon resonance level is determined by two constants: the strong force and electromagnetic force.
  • If you mess with these forces even slightly, you either lose the carbon or the oxygen.

Either way, you’ve got no life of any conceivable kind.

Is the fine-tuning real?

Yes, it’s real and it is conceded by the top-rank of atheist physicists. Let me give you a citation from the best one of all, Martin Rees. Martin Rees is an atheist and a qualified astronomer. He wrote a book called “Just Six Numbers: The Deep Forces That Shape The Universe”, (Basic Books: 2001). In it, he discusses 6 numbers that need to be fine-tuned in order to have a life-permitting universe.

Rees writes here:

These six numbers constitute a ‘recipe’ for a universe. Moreover, the outcome is sensitive to their values: if any one of them were to be ‘untuned’, there would be no stars and no life. Is this tuning just a brute fact, a coincidence? Or is it the providence of a benign Creator?

There are some atheists who deny the fine-tuning, but these atheists are in firm opposition to the progress of science. The more science has progressed, the more constants, ratios and quantities we have discovered that need to be fine-tuned. Science is going in a theistic direction. Next, let’s see how atheists try to account for the fine-tuning, on atheism.

Atheistic responses to the fine-tuning argument

There are two common responses among atheists to this argument.

The first is to speculate that there are actually an infinite number of other universes that are not fine-tuned, (i.e. – the gambler’s fallacy). All these other universes don’t support life. We just happen to be in the one universe is fine-tuned for life. The problem is that there is no way of directly observing these other universes and no independent evidence that they exist.

Here is an excerpt from an article in Discover magazine, (which is hostile to theism and Christianity).

Short of invoking a benevolent creator, many physicists see only one possible explanation: Our universe may be but one of perhaps infinitely many universes in an inconceivably vast multiverse. Most of those universes are barren, but some, like ours, have conditions suitable for life.

The idea is controversial. Critics say it doesn’t even qualify as a scientific theory because the existence of other universes cannot be proved or disproved. Advocates argue that, like it or not, the multiverse may well be the only viable non­religious explanation for what is often called the “fine-tuning problem”—the baffling observation that the laws of the universe seem custom-tailored to favor the emergence of life.

The second response by atheists is that the human observers that exist today, 14 billion years after the universe was created out of nothing, actually caused the fine-tuning. This solution would mean that although humans did not exist at the time the of the big bang, they are going to be able to reach back in time at some point in the future and manually fine-tune the universe.

Here is an excerpt from and article in the New Scientist, (which is hostile to theism and Christianity).

…maybe we should approach cosmic fine-tuning not as a problem but as a clue. Perhaps it is evidence that we somehow endow the universe with certain features by the mere act of observation… observers are creating the universe and its entire history right now. If we in some sense create the universe, it is not surprising that the universe is well suited to us.

So, there are two choices for atheists. Either an infinite number of unobservable universes that are not fine-tuned, or humans go back in time at some future point and fine-tune the beginning of the universe, billions of years in the past.

Why the fine-tuning argument matters

We need to make a decision today about how we are going to live. The evidence available today supports the fine-tuning of the universe by a supernatural mind with immense power. The progress of science has strengthened this theory against determined opposition from rival naturalistic theories.

Those are the facts, and we must all choose what to do with them.

Further study

Here is a paper by Walter L. Bradley that contains many more examples of the fine-tuning, and explanations for what happens when you change the constants, quantities and rations even slightly.
